Philippe Coutinho's move to from Liverpool to Barcelona appears to be increasingly inevitable after reports in Spain claimed the 25-year-old has already agreed personal terms to join the Nou Camp club.

The Brazil international shook hands on a five-year deal with the Catalan giants in July before the Reds knocked back multiple bids from the La Liga giants.

And that agreement remains in place heading into the January transfer window, according to Sport, and Coutinho is keen on completing the move. The same publication reported earlier this week that Barcelona are preparing a new €120m (£106.4m, $139.3m) offer in the winter window in an effort to bolster their squad ahead of the second half of the campaign.

Coutinho is cup tied for the Champions League having played in the competition with Liverpool, but that is not understood to be enough to block the move.

Such is Coutinho's desire to move to Barcelona he has asked his representatives to curtail all contact with officials from Paris Saint Germain in order to speed up his exit from Anfield.

"(He) has asked his representatives to ignore any offer that comes to them," report Sport. "One of them is from PSG. The Brazilian does not want noise, nor third parties, getting in the way of negotiations between Liverpool and Barca."

The former Inter Milan schemer's relationship with manager Jurgen Klopp has broken down after the German coach prevented him from moving to Spain in the summer despite handing in a transfer request.

He has been reintegrated into the Liverpool squad and has been largely impressive while scoring four goals in nine appearance in all competitions. However, the Merseysiders already trail Premier League leaders Manchester City by 12 points and are far from certain of qualifying for the Champions League last 16.

Publicly, Luis Suarez is leading attempts to lure Coutinho to Barcelona after stating that the playmaker would benefit from moving to Catalonia to further his career.

"Obviously he must have because he's a player who has ambition and any player would want to come to Barca," he said. "He went through a difficult and very complicated moment but as a professional he continued to show how good a player he is and the personal quality he has.

"Despite trying to leave Liverpool he continued helping the team and working. He is demonstrating as a professional who has the ambition to take a step further."
